| 摘 要： | 鉴于风电场并网运行对电网无功电压的影响很大,首先分析了风电场并网运行时对风电场以及电网的电压产生的影响机理,探讨了风电功率因数与电网电压波动的关系,并通过实例仿真验证了风电场电压与风电出力、功率因数之间的相关性。由此指出了风电场无功电压控制和无功补偿配置方面的一些对策和建议,要求风电场通过足够的无功补偿配置和无功电压控制策略将其高压母线电压控制在110.0～117.7 kV。

| Abstract: | The wind farm has a great impact on reactive power and voltage when connected to the power grid. Firstly, the mechanism of how wind power influents the voltage is analyzed. Then, the relationship between the power factor of wind farm and voltage fluctuation is also studied. Finally, a case study is carried out to verify the relevance of the wind power output, the power factor of wind farm and the voltage of wind farm. Some suggestions and measures about voltage control and reactive power compensation for wind farm are put forward therefore： sufficient reactive power compensations and appropriate volt/var control strategies are required for wind farms to guarantee the voltages of their high-voltage buses are within the range of 110.0- 117.7 kV. |
